GI Appt for Luke

We went back to the GI dr today for a follow up. He weighed 10lbs even almost 3 weeks ago and today he weighed 10lbs 8.5ozs. He gained, but not nearly enough. He has fallen off the charts completely and officially has the diagnosis of "failure to thrive." It kills me and I literally feel like crying. He's still growing in length (he's 23in now) but his head may not be growing. I personally think they measured it wrong his last appt but now that has to be monitored too.

His Zantac was upped to a higher dose (he gets it 3xs a day) plus now he was given Nexium as well. He's been getting rice in his formula for 2.5 weeks now and obviously that isn't helping! The worst thing was having to tell the dr that "yes, my son is still in pain but he has now gotten used to it." What almost 4 month old deserves to "get used" to pain?

And tomorrow is his 4 month appt and he's getting shots. I feel awful putting him through even more pain.
